I am interested in improvements on Pixhawk orange cube carrier board, I have Pixhawk orange cube REV_E carrier board. I want to design a new PCB to improve myself and add additional features. Since it is open source, I searched on the internet as carrier board reference design and came across this link. GitHub - The Cube
When I examined the documents and the card, I saw that they were two different revisions. A document of REV_C containing Edison in the document in the link. I have the REV_E version. That’s why I can’t understand why the other components around the Ping component are placed and what they do.
Could you please share the schematic documents of the REV_E version?
